i description; i

,satana To all 'whof/niz'mag/ concern.'

Be it known that we, JULIUsPUnn'rZg a citizen of=tliefUnite`d States,anda resident of the cityof New York, borough of `Brooklyn, in thecountylof Kings and State ofNew York, and BAnNnY" Coi-Inma citizen oftheand a resident .of `the city of borough of Bronx, in the county ofBronxand State-ofv New York, have invented a new and ,Improved 1Sad-Iron, of which theifollowing is afulhclear, and eXact United States,

An objectlefthe inventionlisfto providefa simple, le'liicient andinexpensive sad iron within which theflame is gas burner. ult is animprovement over our Patent No.l1,150,703 issued August 18,191.5, y

from which it is characterized by the provision-of a "detachableironingor bottom plate.

vide a sad iron having a detachable ironing plate provided with meansentering the hollow of the iron and subject to the direct attack of theflames of the burner.

Another object of the invention is to provide an ironing plate whichpermits a free access of air through the bottom of the hollow of theiron so as to facilitate combustion within the iron and thereby increasethe efficiency of the burner.

With the above and other objects in view, the nature of which will morefully appear as the description proceeds, the invention consists in thenovel construction, combinawith the Slot `8.

generated i-byr a tion and arrangement of parts as herein fullydescribed, illustrated and claimed.

In the accompanying drawings, forming part of the application, similarcharacters of reference indicate corresponding parts in all the views.

Figure l is a side elevation of our iron partly in section on line 1-1,Fig. 2;

Fig. 2 is a horizontal Fig. 1;

Fig. 3 is a transverse section on line 3-3, Fig. l; and y Fig. 4 is aperspective View of the detachable ironing or bottom plate.

Referring to the drawings, 5 is the hollen7 casing the bottom 6 of whichisprovided with interior transverse corrugations against which the flameof a burner 7 is adapted to play. The bottom has also a longitudinalcentral slot 8 through which air section on line 2 2, 4

tachable bottom plate 1l are adaptedlto en!` ter." 1rFlieselugs 10 arecorrugated to match the corrugations which `corrugated lugs the `flameof the burner is adapted toplay and thereby conveyv the heat directly.`."Iheplate lll'has `a centralgroove12 which is adapted to aline grooves13 leading-from the groove 12ito` the margin of the plate. Thesegroovesl convcyth'cair to thegroove112 from where it enters the slot 8.

Flat surfaces or shoulderswM ofthe plate are adapted to contact with thebottom of the hollow casing, andthereby the ironing directly through thelugs 10, is also heated by contact with the bottom of the casing. Thelugs 10 prevent any lateral or longitudinal move- `ment of the platerelative to the casing. To

retain the casing against the bottom, screws 15 are employed, for `whichthreaded openings 16 are provided in the ironing plate.

The provision of the contacting shoulders 14 gives ample contactingsurface between the bottom and the detachable plateand also assures aperfect bearing for the hollow of the casing, with ample opening in thedetachable plate for the admission of air to the interior of the casing.The detachable plate 11 has also end openings or grooves 17 which leadtothe groove 12 so as to increase the air supply thereto. A

. We claim:

1. A sad iron having a hollow casing the bottom of which has alongitudinal central slot and apertures to each side `of said slot, abottom plate securable to the bottom of the hollow casing having lugsadapted to enter into the apertures in the bottom, and a burner in thehollow of the casing adapted to play its flames on the bottom of thehollow and the lugs of the .bottom plate; said bottom plate havinggrooves from the margin for admitting air to the central slot of thebottom of the hollow casing.

2. A sadiron having a hollow casing provided with a central longitudinalslot and apertures to each side of the` slot, a detachable plate havinglugs adapted to enter the apertures in the bottom whereby "longitudiofthe bottom 6, and against y strilisation-uf Lettersfrateut Patented Ang.13,1918., r yApplicationllewtovlember 10,1917.` \S"e1al\1\o.201,320. y i

It `has also transverse Gili Copies of this patentv may be obtained forand upon the lugs of the plate engaging the` apertures in the bottom ofthe hollow casing, said plate having a central longitudinal grooveadaptedto register with thev slot in theb-ottom of the hollow casing,said plate having also transverse grooves leading from the margin to thelongitudinal groove7 whereby air is supplied to the slot in the bottomof the hollow casing.

Y 3. A sad iron comprising a hollow casing having an internallycorrugated bottom, said bottom' having alongitudinal slot and aperturesto each side of the longitudinal slot, a bottom plate adapted to contactwith the bottom of the hollow casing, lugs on said plate adapted to.project into the hollow of the casing through the apertures in thebottom of the hollow casing, said lugs having a corrugated top, and aburner in said hollow casing adapted to play its llames on thecorrugations on the bottom and the corrugations of the lugs, said bottomplate having longitudinal and transverse grooves for supplying air tothe central slot of the bottom of the hollow casing.

4. A sad iron comprising a hollow casing the bottom of which hasapertures, a bottom platedetachably connected to the bottom of thehollow casing and having projections entering through the apertures intothe hollowvcasing, and a burner in the hollow casing adapted to play itsHaines upon said proj ections of the bottom plate so as to heat itdirectly, said projections presenting a corrugated surface within thecasing to increase the surface upon which the Haines of the burner areplaying.

5. In a sad iron having a hollow casing and a burner in the casing, adetachable bottom plate having projections entering the hollow casing,said projections presenting a corrugated surface within the casing toexpose a larger surface to the flames of the burner.
